How to say 'what is your name' and 'my name is' in French

Answer 1

Hi


How to say "what is your name ?" and "my name is.." in French ?

If you're talking to someone you don't know, you'll use the "vous de
Politesse" (2nd p. plural) or s.o. older than you. More formal than 'TU'

Comment vous-appelez vous ?

If you're talking to so the same age as you = tu 2nd p. sing.
Comment t'appelles-tu ? (not formal) 

s'appeler (present tense)
je m'appelle
tu t'appelles
il/elle s'appelle
nous nous appelons
vous vous appelez
ils/elles s'appellent

note that there is a double  'l" before a mute 'e'


My name is =
Je m'appelle + your name


hope this will help 

Answer 2

This is the answer to your question:

To ask someone their name, a stranger or someone older than you, ask, "Comment vous appelez-vous?". When asking someone your own age, it's "Comment tu t'appelles?

Hope it helps!
